Hi Jazz, that's the red loctite isn't it? Do you use the blue loctite on other bolts in the machine or is bolts loosening due to vibration not such a problem.

Going back to the ATC spindle have you used one of the Mechatron tool change adaptors for a normal spindle which I found on Sorotec's website https://www.sorotec.de/shop/Tool-cha...m-spindle.html. I think that to get started I would prefer a normal spindle to learn the basics of cnc machining and then to upgrade using this adaptor at a later date.

Finally I'm not the best with the electrical side of things. I shouldn't have a problem building a power supply for the drives, but I'm a bit confused with the wiring between the CSMIO and the drive. I was looking at the Lichuan drive and the Leadshine easy servo drive and both seem to accept 24V input with the use of current limiting resistors on the step and direction inputs for single ended. For the differential connection do you not need the resistors as in the data sheets, the differential connections are shown with a 5V connection. Can you not directly connect the drives to the CSMIO, or do you have to reduce the voltage for the differential connection.
